Today I want to talk about Kanna and her hair. The mad dog has straight blonde hair that goes down to her torso. It's very no-nonsense, but it does have a two-tone darkening to brown near the end, like her ears. She has the look of a veteran in that she holds herself straight while also having the aura of having seen things that some shouldn't. The bangs covering her right eye add mystery, while her visible eye has a piercing gaze. Add in the razor-sharp fangs and the cut on her left ear and you have a very menacing face that's good for scaring confessions out of people, not so good at dealing with younger kids. Her ponytail in her swimsuit gives a very mature and practical appearance, as it helps put her hair all in one spot so she can more readily assist if she needs to enter water, or dry it out by wringing it.
She also has two one-shot hairstyles that haven't appeared anywhere else, to my knowledge. The first is in her ID card, showing a very young and equally menacing Kanna, with neck-length hair. It's a very cute way to show who she was, how much she's grown, and what she's kept throughout her time in the KSPD. The other hairstyle is in this 4koma where Kirino ties her ponytail into a ribbon. It is definitely not a hairstyle that fits Kanna, but it is still a very cute hairstyle.
As a whole, her outfit and posture is no-nonsense. Police-blue shirt with a navy tie going straight down, a jacket to indicate affiliation and rank, office skirt, black pantyhose and relatively low heels that she can more decently quick in due to being a balance between office-acceptable and good for chasing criminals.I always found her armband to look nice, as it provides some color to an otherwise relatively normal outfit. Even her halo feels no-nonsense, as this Celtic knot is very square., compared to Fubuki's loose halo, Kirino's halo learning its bounds, or Konoka's almost floral pattern. Something interesting with her is that her wounded sprite has a different pose, while also showing her gun. It's a very good touch, as opposed to having her coffee mug be broken. She also makes being injured look fashionable, perhaps due to her being able to get through dangerous situations.
Again, Kanna is very no-nonsense, and her hair's scent reflects that. She takes care of herself, but also believes in her own "Mad Dog" name that keeps crooks quaking at night. Is there an intimidating smell for females? Probably not, and if there is, I doubt Valkyrie would allow it. So Kanna's hair simply smells clean. She's not going to make it smell nice, she's not going to give an inch to whoever's on her bad side. She does have a soft side, yes, but that's simply something that mere looks can't show. Only getting to know her and earning her trust and respect will do that.
